Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471270, here are decompositions:

  • 53 + 31471217 = 31471270
  • 179 + 31471091 = 31471270
  • 191 + 31471079 = 31471270
  • 227 + 31471043 = 31471270
  • 239 + 31471031 = 31471270
  • 263 + 31471007 = 31471270
  • 269 + 31471001 = 31471270
  • 293 + 31470977 = 31471270

Showing the first eight; more decompositions exist.
